Problems

In the course of using the ''enclosure'' element of RSS 2.0, several shortcoming were reported:

• It is only defined for RSS 2.0. There is no formal definition of similar element for RSS 1.0 and ATOM.
• It only allows simple flat lists of enclosures. It does not allow one to specify alternative formats, group enclosures, or specify relationships between them.
• It does not support any kind of non-abmbigous identification of individiual enclosures for the purpose of referencing them.
• It does not contain any means of specifying relationships between syndicated content and enclosure.
• It does not allow the specification of multiple alternative download locations.
• It does not allow the specification of download locations using file sharing protocols like BitTorrent.
